DRAIN-VALVE.

Specification of Letters Patent. Patented Sept, 14, jlgfiili,

Application filed September 6, 1907. Serial No. 391,619.

To all whom it may concern:

Be it known that I, HOWARD M. KIRBY, a

citizen of the United States, and a resident of Wilmington, in the county of Newcastle and State of Delaware, have invented a new and Improved. Drain-Valve, of which the following 15 a full, clear, and exact descrip-.

tion.

This invention relates to drain valves, and is especially adapted to be used in connection withbathtubs, wash bowls and the like.

The object of the invention is to produce a valve of simple construction, having means for normally holding the valve wide open,

. the valve having such a construction as will enable the valve to'be locked by a simple movement, in its closed position.

Theinvention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the'accompany ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

- Figure 1 is a vertical section through the.

edge and bottom of a tub to which the invention has been applied; the lower portion of the valve is shown in crosssection and the other parts are shown in elevation; Fig; 2

is a vertical section throughthe lower portion of the valve, upon an enlarged scale,

and showing the parts inthe relation they assume when the valve is closed; this view is a section on the line 22 of Fig.3; Fig. 3 is a horizontal section on the line 3-3 of Fig. 2; and Fi 4 is a vertical section through the ban le of the valve; that is. at the upper edge of the tub, from which point the-valve is operated.

Referring morefparticularly to the parts,"

body is connected with an overflow pipe 7 which extends vertically upward, and 1s connected with the overflow drain or outlet 8 mounted in the side of the tub, the connection at this point being effected by means of a suitable elbow 9-.

The lower side of the valve body a is connected with the drain pipe '10. The interior of the valve body 41 at its point ofconnection with the drain connection 5, is formed into a valve seat 11, as illustrated most clearly in Fig. 2. In the interior of the valve and in the upper portion thereof, an car 12 is provided, to which avalve lever 13 is pivotally attached. The lower end of this valve lever 13 is rigidly connected to'a valve disk 14 which is of roundedor cup form, the convex side of the cup being disposed toward the drain connection 5. On the inner face of this valve disk 14 a washer or packing cup 15 is attached. As illustrated, the diameter of the disk 14 is considerably less than that of the seat 11, so that the edges of the packing cup 15 project beyond the disk 14 and come against theseat 11 as shown. To the end of thelever just behind the central point of the disk 14, astrut or link 16 is pivotally attached, and the interior of the valve body' opposite to the central point of the disk 14:, is provided with a shoulder or stop 17 which projects inwardly as shown. Just above this stop 17 a small recess or groove 18 is formed in the wall of the valve body, which is slightly increased in thickness at this point as shown. The free end of the link 16 is rounded as shown, so that when the valve is closed, the link lies in a horizontal position, its free end being held in the groove, recess or notch 18. In this connection, it

v will be understood that the resiliency of the packing cup 15 insures that the link will hold itself in position as shown. I

Near the middle point of the link 16, a saddle 19 is pivotally attached, and this saddle is provided with a threaded bolt 20. To this threaded bolt 20 a valve stem 21 is attached, the connection including an enlargement or-head 22 formed on the body of the ment in the guide openings Having thus described my invention, I

number as shown. These teeth are adapted to'be received in notches 26 formed in a knob seat 27 which knob seat is attached to the.

upper side of the flange of the tub, being formed with a suitable nipple 28 which passes downwardly through the opening 23' and receives a clamping nut 29, as shown most clearly in Fig. 4. Between the adjacent faces of the knob and knob seat, a spring chamber 30 is formed, in which there is received a helicalspring 31. This spring is a compression spring, and tends to hold the stem in a mu'ch elevated position, as indicated in Fig.1. This position of the stem holds the valve in a wide open position, the opening movement of the valve being arrested by the stop or projection 17 which is struck by the lower edgeof the packing cup 15. The teeth 25 and the notches 26 have inclined meeting faces assh'own.

In order toclose the valve, the knob 24 is pushed downwardly so that the link 16 moves down into the horizontal position shown in Fig. 2. In doing so, the end of the link 16 snaps into the detentnotch 18 intended to receive it, and this holds the valve in its closed position. When the valve is to be opened, a slight rotation of'the knob operates to draw the stem 21 upwardly, by reason of the fact thatthe inclined edges of the;

teeth 25- slide on the inclined edges of the notches 26. In this way the opening movement of the, valve is initiated, and. enables the end of the link 16 to free itself. As soon as this occurs, the sprin 81. extends itself and opens the valve to t e'wide open posi-' tion.

Special attention is called to the fact that when the valve is closed, the overflow pipe is unobstructed. When the valve is closed, it will be observed that the link 16 operates as a strut, jammed as it-'is .between the back of the disk and the valve body.

The fact that the link 16 is pivotally atachedto the valve disk, enables the stem tooperate it by arsimple longitudinal moveor thestem.

claim as new and desire to secure by Letters. Patent:'

1. In combination, a valve body having a valve'seat, a movable valve disk adapted to close, against said seat, a stem, a member connecting said stem with sald'valve disk, and pro ect1ng across the lnterlor of said said stem tending to raisethe same and hold said valve disk open, said body having a recess adapted-to receive the end of saidgmember when said disk is moved to its closed position, said member beingadapted'to snap into said recess whereby said body affords means for holding said member against the force of 'said'spring,

2. In combination, a valve body having'a ,valve seat, a valve disk pivotally mounted within said body and closing'upon said seat, a link pivotally attached at the back of said 'disk and extending across the interior of said body, a stem pivotallyattached to said link, and a spring in'connection with said stem tending to raise' the 'same and 'open said spring afiording means for opening said disk when said link 1s released from said detent means.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
